' SPECIFICATION forming part of Letters Patent No. 763,484, dated June 28, 1904. Application filed January 8, 1904. Serial N0. 188,200. (No model.)

To all whom it may concern:

Be it known that we, BERNARD J. HAUSFELD and EDMUND H. LUNKEN, citizens of the United States, residing at Cincinnati,Ohio, have invented certain new and useful Improvements in Window Constructions, of which the following is a specification.

Our invention relates to window construction for buildings of the general class disclosed by the sashes and means, in the nature of weatherv after described, and particularly pointed out whichis of metal, U shape in cross-section,

strips, whereby tight joints are maintained between the contacting moving parts.

The invention consists in the features, combination, and arrangements of parts hereinin the claims.

In the accompanying drawings, Figure 1 1s gears for connecting the same with thesashes,

said view being substantially on the line 2 2 of Fig. 3, thegearing, however, beingshown i for convenience in elevation, this View showing our invention applied to a stationary i frame. Fig. 3 is a detail horizontal sectional view through one side of the swinging frame on the line 3 3 of Fig. 2. Fig. 4 is a detail sectional View of the upper part of the swinging frame and the upper sash. Fig. 5 is a detail sectional view through the lower part of the swinging frame and the'lower sash. Fig. 6 is a horizontal view through a window, showing another embodiment of our invention, and illustrates the swinging frame vertically pivoted.

In the drawings,.1 designates the main frame,

bead or strip is secured by screws 8.

and adapted to be secured in any suitable way within the window-opening. The secondary or swinging frame is designated generally at 2, and it comprises, as shown in Figs. 3"and 6,

side pieces 3,formed, preferably, of metal and of U shape in cross-section, and a bottom piece t. Within the side pieces 3 a hollow parting strip or bead 5 is arranged, which is also of general U shape in cross-section, having outwardly-turned flanges 6 bearing against the inner sides of the U-shaped side pieces 3 and held in place by a bar 7, whichis secured by screws 8 to the'U-shaped side piece of the swinging frame and to which bar the parting This supporting-bar 7 is of I-iron shape in crosssection, as shown in Fig. 3, and it fits within the hollow of the parting bead. or strip 5.

As shown in Fig. 2, the supporting-bar 7 extends vertically from the top to the bottom of the swinging frame-and strengthens the same, besides serving as a means for supporting the hollow bead.

As shown in Fig. 3, spaces 9 are left between the outwardly-tu'rned flanges of the 1 parting-bead and the bottom of the U-shaped a vertical sectional view of one embodiment of ourinvention, showing the secondary frame horizontally pivoted. Fig. 2 is a vertical sectional view through one of the weight-boxes, showing the sash-balancing'weights and the:

side pieces of the swinging frame, and we thus provide boxes in which weights 10 are slidably arranged, said weights being provided with teeth 11, meshing with toothed wheels 12, which are on a shaft 13, bearing in the I-iron bar 7 and in blocks 14, secured to the opposite sides thereof. These gears also mesh with teeth 15 on the side pieces 16 of the sashes,

weights 10,'connected thereto by the gears,

the said weights running in the weight-boxes .9. It is thus clearly seen that the advantages derived from having the weights operate with the sash are, first, that in horizontally-pivoted frames unless such means as this were employed the weights and sash would by gravity fall to the bottom of the window when the frame was reversed, and, second, the inconvenience of broken cords or chains, which are'of frequent occurrence, is overcome, the rack and pinion being of a nature much stronger and durable.

The sashes, it will be understood, are arranged to move one on one side of the parting bead or strip and the other on the opposite side thereof, and each sash is proi' ided with a removable plate 18, held to the side rails or pieces 16 of the sashes by screws 19. These plates or pieces 18 extend within the U-shaped side pieces of the main frame close to the outwardly-turned flanges'of the parting-bead, which flanges, as indicated at 6, lie slightly within the edges of the U-shaped side pieces 3 of the swinging frame.

In order to provide means for maintaining tight joints between the fixed and movable parts, we employ the stops 20 and 21 on the fixed and swinging frame, respectively, these being substantially the same as those disclosed .in the applications above referred to, and in addition to these we provide special weatherstrips or closing means for the joints between the sliding sashes and the adjacent fixed parts of the swinging frame. As shown in Fig.- 3, a strip or sheet of brass or other suitable material 22 is clamped between the side piece or plate 18 and the rail or side 16 of the sash, the said sheet-extending along the inner side of the removable plate 18 around its edge and in between its outer face and the inner face of the flange 24 of the U-shaped side piece 3 of the swinging frame. The end or edge of this brass sheet is not connected to the plate 18, but is left loose, so that its natural flexibility or spring will tend to throw it outwardly toward the inner face of the flange 24, and thus close the crevice at this point against the entrance of air or dust. Another sheet of brass is clamped between the side rail 16 of the sash and an inner strip 25, which is secured to the rail 16 by rivets 26, as indicated in dotted lines in Fig. 3, and this latter strip or sheet of brass extends between the inner side of the sash and the opposite face or side of the parting-bead 5, as shown at 26, its end 27 being loose, so as to spring toward the parting-bead and make a tight joint between the same and the sliding sash.

In addition to the Weather strips or sheets just described we employ another sheet of brass or like material 28, which extends around the faces of the parting bead or strip, thence along the inner faces of its laterallyextending flanges, from which it continues along the inner faces of the flanges 24 on the U-shaped frame sides and in contact with the loose ends 23 on the brass sheets 22, be-. fore described. These ends or edges 29 are also left loose in order that they will accommodate themselves to any looseness of the sashes, and thus by their natural flexibility close up any spaces whiclrwould otherwise exist between the sashes and the runways or guides formed in the U-shapcd side pieces of the frame. This same idea is carried out in connection with the upper and lower edges of the sashes, as illustrated in Fig. 4 and Fig. In the latter. figure the loose end of the sheet of brass or other material is indicated at 30, and in order to shield this loose end or edge when the lower sash is raised we provide a strip 31 on the lower sash directly over this loose portion, so that no damage will result thereto and the hands will not come in contact therewith.

The above sheet-metal strips not only serve the purpose of weather-strips, but also form good wearing-surfaces between the sash and frame when the strips are made of brass, as in the preferred material, and the unsightly appearance of rust along the bearing-surface, as would be the case when made of iron, is overcome.

It will be noticed that the frame in which the sashes slide is divided or partitioned oil by means of the laterally-turned flanges of the hollow parting-bead, so that weight-boxes are provided on one side of the said flanges and guideways are provided on the other side of said flanges.

As will be readily understood, our invention can be applied to stationary and vertically and horizontally pivoted windows and can also be applied to that form of window in which the main frame is stationary and the sashes swing independently of each other. In the lastnamed construction the guidebar of the swingingsash, which always remains in the guideways of frame even when sash is swung open, can have the rack attached thereto, with which the pinion engages.

WVhile our invention will entirely be made of metal in its preferable construction, yet it will be readily understood that metal racks can be applied to wooden sash and the invention adapted to wooden construction, the same results being obtained.

We claim as our invention- 1. In combination, a swinging frame horizontally pivoted, a pair of sashes slidably arranged therein and constant balancing means for the said sashes to maintain a balanced control thereof in all positions of the swinging frame, said means comprising a toothed weight for each sash and a toothed wheel meshing with the teeth of the weight and with teeth on the sash, substantially as described.

2. In combination in a window construction, a pair of sliding sashes, a metallic U-shaped frame, an I-iron secured centrally within said frame, a hollow parting-bead secured to the I-iron and having lateral flanges within the U-shaped frame, toothed weights in the boxes formed between said flanges and the U-shaped frame and I-iron, racks on the sashes, pinions engaging the racks and toothed weights and a shaft or bar passing through the I-iron and parting-bead for supporting the pinions, substantially as described. 3. In combination, a pair of sashes, a U- shaped frame in which the said sashes slide, partition means for dividing the space within the frame into weight-boxes and guideways,

weights in said boxes, means connecting said 5. In a window construction, a sash comprising the glass, the rails and a removable piece for retaining the glass in place with a sheet of metal clamped between the said removable piece and the rail and extending to the outer side of the sash to form a tight joint between the sash and frame, substantially as described.

6. In combination'in a window construction, a sliding sash,-- a frame, a sheet of material having a loose end or edge between the said parts and a shield extending along the said loose edge or end, substantially as described.

In testimony whereof welaflix our signatures in presence of two witnesses.
